It's honest to say that soup season has begun. Even though we are having a particularly warm season so far. When you're craving something hot and comforting but still want to be healthy, this is a perfect soup and it's very fast to make. Based off a traditional Italian soup called "Zuppa di Scarola e Cannellini".
Another great thing about escarole is that unlike kale it is still reasonably priced. Kale is on a serious trend right now and prices are from 4-5 dollars (at least here in NYC) and you can find escarole for as little 2 dollars. Escarole is grown in very gritty soil. Its important to throughly wash it so you don't end up cracking your tooth on a small pebble. I wash it 2-3 times in a salad spinner and double check the leaves to make sure that I have missed any dirt.
1 can of organic cannelini beans (any white bean would be fine)
1 head of escarole
1 cup of white wine
3 cloves of garlic
1 small yellow onion (or half)
few spring of fresh rosemary (or any savory herb)
2 celery stalks
sea salt & pepper
